im not quite sure. but if it was me, bat magic is very important. I want bat magic more than anything (almost) im a collector of magic, and all i dont have is inferno bat n snowman. So unless bat gets re-released at halloween it might someday be as rare as inferno!
Bat will probably not ever be as rare as inferno =/ considering inferno is only given out in special events i dont see how its possible unless inferno was released..i guess its a good trade if you need that stuff but i dont like trading for a bunch of lesser value things for one quality thing unless u need the stuff.
